You're doing a great job caring for her.
The wounds look quite small and pretty straight forward to address, as long as her body cavity and organs weren't pierced. Even then everything is indicating she's going to make a nice recovery.
My concern with Blue Kote is that the color could mask infection and bruising, both telltale signs of how she's progressing. And I recently read some comments that indicate Blue Kote stings and can add to a chicken's stress.
Neosporin is a favorite in the forums, but there are actually lots of options. Raw, unpasteurized honey is an excellent healer. Do give her daily warm epsom salt baths, full body. You can use a wash cloth to saturate her wounds repeatedly and to flush under her wings and other feathers. The salt soaks will also help with other wounds you may not have discovered just yet.
Considering the size of the wounds, she probably can be returned to her flock soon, but personally I would keep her in a warm room or a make shift coop or brooder in a garage for a week. My feeling is that warmth comforts injured chickens and can help them relax and aid in the healing process.
Should one of the wounds open and begin to bleed, unbeknownst to you, the others will peck and dig and exacerbate the injury. That's why I feel reintegration with the flock should be delayed.
But supervised visitations with her hens are important to maintain her need to socialize with them. They are prone to depression, just like any creature. You can bring one to visit while you knit or read a book, and if possible give her a view of the chicken run.
I would continue to feed her cooked eggs or canned tuna or salmon to boost her daily protein intake. I learned in the forums that increased protein aids with the body's ability to heal itself.
As for the other hens, when my rooster was attacked by a coyote a few months ago, the ones who were laying eggs stopped. They exhibited signs of stress for a good week or so, and continued to be cautious and watchful and unsure of themselves without Henry during his recovery.
How are her legs and ability to walk?
